A Florida student, 15, was arrested this week for putting hand sanitizer in a teacher’s Diet Coke can, police report.

Nicholas Lucari is facing a felony charge for allegedly squirting “Germ-X” into Dale Dawson Yount’s drink. The South Walton High School teacher, 69, subsequently “became physically ill” and she sought treatment at a local hospital, according to a Walton County Sheriff’s Office report.

Investigators allege that Lucari, pictured above, “did willfully, intentionally, and with the intent to injure” add the hand sanitizer to Yount’s beverage. As a result, the teen was busted on a poisoning rap.

Lucari, cops noted, has been “suspended from school pending an expulsion hearing.” The student has been described as a “prankster” who did not intend to harm Yount, who is seen at left.

Like many hand sanitizers, the active ingredient in “Germ-X” is ethyl alcohol.
